Building Permit Leads vs Home Sale Leads: What's the Difference?

If you're exploring public records as a lead source, you've probably come across two main types: building permit leads and home sale leads. Both come from public government records. Both are legal to use. And both represent real people who are about to spend money.

But they work very differently, and one might be way better for your business than the other. Here's how to think about it.

What building permit leads tell you

A building permit lead is someone who has filed a permit to do construction work on their property. The filing tells you the property address, the type of work (kitchen remodel, roof replacement, pool installation, new construction), the estimated project value, and sometimes the contractor of record.

The key signal here is intent to do a specific project. When someone pulls a permit for a $45,000 kitchen remodel, they've already committed. They've paid the permit fee, submitted plans, and they're doing this work. The only question is who's going to do it.

This makes permit leads incredibly targeted. If you're a plumber and you see a kitchen remodel permit, you know with near-certainty that the homeowner needs plumbing work. There's no guessing.

What home sale leads tell you

A home sale lead is someone who just bought (or sold) a property. The deed transfer record tells you the property address, the sale price, the buyer's name, and the closing date.

The signal here is life transition. Someone who just bought a house has a long list of potential needs: locks changed, house cleaned, HVAC inspected, landscaping, painting, pest control, insurance review, and eventually renovations.

Home sale leads are broader but less specific. You know the homeowner is likely to spend money on their home, but you don't know exactly on what — or when.

Which is better? It depends on your trade.

Here's a rough guide:

Permit leads are better if you're a trade that serves specific construction projects. Plumbers, electricians, HVAC technicians, roofers, and painters all benefit more from permits because the lead comes pre-qualified. You know the project type, the budget, and the timeline.

Home sale leads are better if you serve a need that comes with moving. Locksmiths, cleaning services, movers, pest control, insurance agents, and landscapers all benefit more from home sales because their service is tied to the event of buying a house, not to a specific construction project.

Both work for general contractors, handymen, and businesses that cover a wide range of services. More data points mean more opportunities.

Timing differences

Permit leads have a tighter action window. Once a permit is issued, work typically starts within 2-6 weeks. If you don't reach the homeowner (or GC) within the first week or two, you've probably missed the window for that specific project.

Home sale leads have a longer but more gradual window. The buyer's needs start on closing day (locks, cleaning) and extend over 12 months (renovations, upgrades). You can plan a multi-touch outreach campaign that hits different needs at different times.

Volume differences

In a typical Orlando-area zip code, you might see 30-60 home sales per month and 15-40 building permits per month. Home sales tend to be more consistent; permit volume can fluctuate seasonally (more in spring and fall, fewer in deep summer and winter).

If you're monitoring 15 zip codes, you're looking at roughly 450-900 home sale leads and 225-600 permit leads per month. That's a lot of opportunity from just two signal types.

The case for using both

Here's what most people miss: you don't have to choose one or the other.

A home sale often leads to building permits 3-6 months later. The new homeowner settles in, decides to remodel the kitchen, and pulls a permit. If you've already reached them when they bought the house, you're the first contractor they think of when the project starts.

Using both signal types gives you two bites at the same apple. First contact on the home sale, second contact on the permit.

ZipSignal lets you monitor both simultaneously. On the Growth plan ($49/month), you get all signal types — home sales, building permits, and new business filings — across 15 zip codes. The AI tells you which leads are relevant to your specific industry regardless of the signal type.

Adding new business filings to the mix

There's a third signal type that most people forget about: new business filings. When someone files an LLC, incorporates, or registers a new business, that's a public record too.

New business filings matter to CPAs (every new business needs an accountant), attorneys (formation docs, operating agreements), web developers (every new business needs a website), insurance agents (commercial policies), and commercial service providers (cleaning, security, IT).

If you serve businesses, this third signal type opens up a whole pipeline that permit and home sale leads don't touch.

The bottom line

Permit leads give you precision — you know the project and the budget. Home sale leads give you breadth — you know someone's about to spend money on a dozen things. New business filings open up the commercial market.

The best approach for most service businesses is to use all three and let AI figure out which ones are relevant to you. That way, you're catching every opportunity in your zip codes, not just the ones that happen to match a single signal type.
